The Journal «Izvestiia Rossiiskoi akademii nauk. Mekhanika zhidkosti i gaza » (The news of the Russian Academy of Sciences. Mechanics of liquid and gas) was founded in 1966. The journal publishes articles on the problems of fundamental research of classical models of ideal and viscous incompressible liquids and perfect gas; Studies related to the complication and improvement of these models for the description of special classes of flows that are interesting from a practical point of view (the motion of bodies in water at high velocities, turbulent currents, currents of chemically reacting gas mixtures, multiphase flows, stratified fluid flows, boundary layer flows, flow in microgravity, etc.); research on the development of new models that allow describing the flows of liquids and gases under conditions characteristic of the "science interface" (the motion of viscoelastic media, magnetohydrodynamic flows, electrohydrodynamic currents, biomechanical currents, etc.); research in the field of current stability; the study of models of turbulence and laminar-turbulent transition, etc.
